' To all Iwhom, t may concern.'

Be it known that I', HENRY C. Osonn, a`A citizen of the United States, residing at Cleveland, inthe county. of Cuyahoga and State of Ohio, have invented a. certain new and useful Improvement in Printing Mechanisms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

i The object of this invention isto provide in a simple and elicient form, a printing machine of a rotary type wherein the printing forni is planular. By this combination, I obtain the continuous drive which is characteristic of rotary machines and also the ,ability to vuse ordinary printers type or flat electrotypes. I accomplish the desired result by moving the platen in a circ-uit and swinging the type bed correspondingly, whereby the platen rolls over the bed in contact from end to end and causesq the proper impression. This broad feature and other features contributing to the eiiciency and simplicity are comprised within my invention, and are illustrated in the drawings and hereinafter more fully explained.

In the drawings Figure 1 is a. side elevation; Fig. 2 is a front view partly sectional; and Fig. 3 is a plan.

The frame of the machine, as shown, comprises a suitable base 10 from which rise standards 11 and 12. Mounted above the base is the type bed 14. This bed may consist of a tray, as shown, adapted to carry type 15 locked therein in the usual manner to make a page form, as shown 1n Figs.

l and 2. The bed is pivoted by studslG,

in suitable ears 17 constituting a portion of the frame. |The axis of these studs alines with the face of the type.

Journaled in the standards 11 and 12 is a shaft 20, -on which are rigidly mounted aims 21 and 22. These arms carry near one end the rotary platen 24 and near the other the corresponding ink roller 25. ln the upper part of the macliineis a suitable inking disk 26 adapted to carry ink on its under face. rI'he shaft 20 provided with a. crank 27, and when this crank is driven, the two rollers travel through a circuit and in doing so the inking roller 25 takes ink from the disk 2G and app-lies it to the type and thereafter the platen roller impresses paper laid on. the form onto the same. Both the inking disk and the type bed swing to cause proper contact of the rollers andv means are provided to prevent the platen roller being inked by the disk. The mechanisms for controlling these operations will now be described.

Depending from t-he type bed .14 is an ear 30 to which is secured a spring 31, the other end of which is anchored to the 'base as at 32. The eifect of this spring is to give the type bed a tendency to assume an inclined position shown by the dotted lines in Fig. 1, being adjusted by the stop screw 34y mounted in the frame. lThis inclined position of the bed is such that as the-platen roller comes downwardly toward the bed, before it engages the type.I rolls 35 on the arms 21 and 22 pass under'the ribs 38 on the side of the type bed. The under sides of these. ribs are so formed (in a curve which approximates a straight line, as shown) that as the rollers travel along under them, the face cfthe contacting line of type is maintained thereby at-aconstant dist-ance from the platen axis. -This action causes the platen and the inking roller to vmaintain the desired contact with the typein the bed. As soon as the rolls have cleared the ribs 38, the type bed swings back into position shown in dotted lines in Fig. 1.

The inkipg disk is mounted by means of a swivel stud .40 in the rocking frame 41 which is pivotally mounted on studs 42 in ears 43 depending from a cross bar 44. This cross bar is supported by means of rods -46 I vertically slidable in ears 47 and 48 on the standards 11 and 12; the cross bar is pressed upwardly sufficiently to counterbalance its weight, by springs 49, and cams 50.011 the shaft 20 operated at the proper time move the crossbar up or down.l The .cams are shown as disks having grooves 51 in which 'take contact rollers 52 on the lower ends `of the rods 46.

The v'disk 26 is normally held in inclined position approximately parallel with the bed 14 by the spring 55, which is anchored at its upper endto the cross bar 44 and at its lower end to anarm 57 projecting from the swinging frame 41. A suitable stop screw 58 limits the movement ofthe disk. In this position of the parts,v whenQthe inking roller approaches the disk the rolls 60 on the arms 21 and 22 engage the up' per edges of ribs 61, (similar 'to the ribs 38) on the sides of the swinging frame 41 and' this position,the .elevation of its lett hand-j portion causes the pawl 65 pivoted to the cross bar flt to click over the next tooth of a series of ratchet teeth 66 arranged inta circle about the upper face of the inking disk. the disk and the latter swings back into position under the influence of the springl 55, t-he pawlanchoringthe engaged ratchet tooth causes the disk-to turn on its swivel 40, Accordingly, :the disk is periodically fed to present the ink thereon diiterently to the inking roller giving a proper distribution, as will be well understood. While the inking'roller is traveling past 'the disk 26, the rolls 52 are each in a concentric portion 71, of the cam groove 51, which has a comparatively small radius whereby the disk is held down to the position throughout this portion v ofthe travel of the'inking roller. After the inking roller is moved beyond the disk, the portion 72` of the-cam groove engages the roll 52 and elevates the cross bar 44, the frame il and-the inking` disk so that the platen 24 andthe rolls 35 may 'pass idly beneath the same without contact therewith,-this idle passage being while the concentric portion 78 of larger radius of the cam groove is coperative with the roll 52. After the platen has moved past the inking disk thedecreasing portion 74C of the cam groove brings the disk back to position for engagement.

ln order that the inkin'g roller may properly take its ink and Vink the form and in order that the platen roller may properly impress the form, it is desirable that these rollers be positively rotated as they come into action. Accordingly, l provide the rollers 24 and 25 with pinions 77 and 78A rigid therewith which constantly mesh with an internal gear 79 carried by suitable standards 18 and 19 rising from the base. This gearing causes the rollers Vto turn on their axis as they travel.

in the operation of my ,machine` the type form is made up and locked in the bed in mrthe usual manner and the ink is supplied to the disk by an ink knife or otherwise in the usual way, and by means ot the crank 27"', the trame carryingthe rollers is rotated.

litter the inking roller has inked and cleared Y the type bed and beiore the platen roller en ages it.r a sheet of paper is laid on the which it at this time occupies the position shown in dotted lines in Fig. l. Owing to the open space above the type bed when rlhen when the -inkingroller clears inaaeor the two rollers are approximately in a horizontalplane over the shaft 2O there isplenty of room and time for supplying the paper. kby hand, even though the machine be driven with comparative rapidity. 'A

lt is to be understood also that numerous adjustments for the various parts to cause and maint-ain the proper present-ation of the 'rollers andfothe'r coperating parts will be supplied by the skilled mechanic in construct-ing the machine shown, and are.

omitted from the illustration tor the sake of simplicity.'
